i dont tell anybody in real life unless they specifically ask.
i don't want to use it as an excuse, and i dont want anyone else to do the same either consciously or sub-consciously.
however i do tell people about how it affects me, like i dont really like loud noise, i like being on my own and go for walks etc, and im shy and everybody seems to be okay with that. if people ask why one of these things affects me, especially when it comes to my senses then i just say i, like everybody perceives things differently (a great example i use is my eyesight, and spatial awareness (or lack of it) without my glasses). it prevents what i stated above, prevents misconceptions and they are more likely to understand what im saying and how it affects me (and how they might be able to relate to it) than if i just said i have autism.
